To all wle/ont it may concern:

Be it known that I, ANDREW BURGEss, o citizen ofthe United States, residing at Owego, in the county of Tioga. and State of New York, have invented certain new and useful Improvements in Magazine Fire-Arms, of which the following is n specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a simple und rapid magazine arm which can be operated by the fingers of one houd; and it consiste in various improvements, some of -V v which were applied for by me August 14, 1884',

Serial No. 140,499, and of which ense this isjiL part e division.

Figure 1 is e longitudinal sectional elevation of this arm, showing the general arrangementof parts, with a link-connection ofoperating-lever und brace. Fig. 2 is a view from the front of e cross section on theline xx, without the cartridge, of Fig. l; Fig. 3, u View of tite carrier detached; Fig. 4, a horizontal side section of the frame; -Fig. 5, an open view of the arm, partly in section, with some mod- Fig. il shows o cross-section of bolt andiiring-pin with its washer.

'A is the frame; B, the bolt; B', the lockingbl'ac'e; G, the carrier; L, the lever; F, the firingpin; l), the extractor; D, the cookingpiece; T, the trigger; the shoulder on trigger-lever to engage the cooking-dog; t', the dog that holds the trigger forward inthe lever;

't, a shoulder to release it; t2, e lever to reits top, which project into grooves in the bolt.

a c are ledges on inside o frame to support the bottom of the bolt.

I) is :in enlarged passage from the magazine into the frame; b', an upward continuation of scid passage, and b2 a groove to allow the passage of the cartridge-flange up through the top of the frame.

f shows projections in the bolt to rebound the firing-pin, and f the star-shaped washer on firing-pin. (See Fig. 6.)

A reciprocating bolt is honsedon the frame to be locked and moved through its brace B by a lever, as L, which forms a handle and guard and carries the trigger T. The guardlever is connected to the brace bythe link L', as in Fig. l, or by o slot and piu, as shown in Fig. 5, so the backward movement of the upperarm of the guard-lever unlocks the brace by its connection, which pulls obliqnely back and downward 0n said brace, and then moves K back the bolt' to open the breech, which nifty then he closed and locked byu reversal of this movement.

The firing-pin F is arranged in the bolt to be propelled forward by a spiral spring, as in Fig. Land projections, asf, n'rc fixed inside the front of the hollow of the bolt which contains the spring to stop said spring when it reaches near its foremost position, so the tiring-pin may have o slight rebound and will bear on the cartridge only by momentum acquired by the quick force of the spring before it reaches the stop f, and in a' manner well known in relioundng-locks.

The washer j", fixed to the iringpin, has two or moreprojections, which support the forward end of the spring, that it may thereby 'drive the pin forward until the spring stops against the prQicctionsf/of the bolt.

The trigger T is pivoted in thc operatinglever L. The trigger is normally locked to thelever, so as to be rigid therewith, by means of u spring-dog, t', shownin Fig. l as pivoted and in Fig. as a sliding dog, t5. Nhen the lever is swung buck, the spring-dog engages au incline, t, on' the frame, which trips it, so as to permit thetrigger to rock in the lever on its pivot. The farther backward movement of the trigger brings its` shoulder t against a cockinglever, D, pivoted -in the frame.

As shown in Fig. 1, the lever YD beers against the firing-pin, and has a lever?, t, pivoted in itself. The engagement of the trigger is by the shoulder t bearing against the lower end of the lever t2, and, :is said lever t2 has a bearing against thelever D, the 'lever D must rock with it. When the end of the lever t strikes thehearing fin the fraine,thelever L'` is rocked on its pivot until it is ont of-contact with the trigger, when the lever D is free lo move and permits the iiring-pin to fall.

.ln lfig. 5 the lever 152v is omitted, and the backward movement of the cooking-lever l) .is ell'ected by direct engagement with the trigger. The lever D turns back so far as to rock out of engagement with the iiringpin to release the same.

I do not specifically claim the mechanism lor drawing back the firing-pin' or hammer.

A spring-rod, S, is arrangel'l alongside and parallel with the barrel, with its rear end in engagement 'ith the front of the cartridgellange or face ofthe bolt, so that when the boltl unlocked the pressure of-the spring-rod S 'dri baek or assists to drive back the bolt to open the breceli, so that less power is required lio open the arm, and the springpin S will be again forced forward by the closing breech.

rlhe frame is constructed narrow at the rear of magazine and barrel,v so as to admit only the body and not the flange of a cartridge, c )ling in theenlargcd portions Z1 b2 and the pace for the tlat sides ofthe bolt, sot-hat` the cartridge in ieeiling rearward i're'in`the magazine i. first guided back onto the carrier ny its iiangesmhich moves in the depression b, and is h eldtherein by the narrow part above n ntil the flange reaches the vertical depression b', threngh which it is 'then raised by the carrier into thc wider part of the frame, (which is the path of the bolt,`) and it is prevented from flying ont of the frame by the flange striking the projections a, o7 or narrowing part of said lop, and, the solid part forward stops the point oi' the cartridge, and the ledges eo will snpport the llange of the cartridge as it starts forward, (if the carrier ialls,) and the inclined parts ol' the said ledges raise the rear of the cartridge as it moves forward to enter the barrel. Grooves are made in the sides of the top el' the bolt to admit the proieetions La of the ,"ran'ie.4

The exploded shell is extracted as the breech is opened by a springhook at the bottom of thebolt7 and as the llange bears againstthe narrow part or projections a a in the' top ol the frame it held down. thereby until it rea-ches the depression b", which forms :in npivard passage, through which it is ejected' by,

the extractor, or the raised part c ot' the earrier springing np 'against the bottom of the liazpgc, or by another cartridge rising upward on the earl-ier against it.

It will he seen that the passage b thronglr the top et the frainc is so far rearward ofthe passage b', (above tfno inngazi ne,) that the feed* ing cartridge hcpt so far forward hy the `er;tractor that its llangeveannot enter lheerc 'iingpassagc lf', but wiliihestopped fmiir igloo l'nr by the. projection inheritor@ of thezarrier to strike the extractor whe-litho Another?proiection, e, is formed on the topA "7T-c1: `pivotell .in the freine, which. ini.

carrier rises to expel the shell. this may be used in conjunction with the projection e@ (which strikes the bell ein oi' the shclh) er :is a substitute therefor. in this construction the frame the narrow part fr (f, heidi-f. the can tridgc Clown against the extractor in tien ol' the ordinary stud, proieeting i'reni the lat-e ol the bolt and permits the direct expulsion side4 wise of the cartridge or shell witheiit the nsna tripping movement, and this arrangement may bc used in substantially the saine manner through the side instead of the top of the frame.

The carrier is pivoled in the iraine rearward of the lever and has'one side ent away or avertieal slot for the lever to weri; iin The carrier has a joint ol' limited movement, as shown in Fig. Il, at or about the rearniost point reached h v the Coleridge-heini, se that the forward part oll ,'arricr in-ty remain down while the iniddiv part raised little, and lr, raising lhe middle part oi'joint of the carrier to align the hcanl ol" the :farti-ill with the barrelI glie forward lzvnrt taking a leerer posilion than i c ol' :i righi carrier, 'clins presenting the cartridge less molifpzolj: to the eliainher ot' the erin.

'lhe top of the traine has a solid part under the rear of the boit through which it isserewed vertically lo the upper errear tang or strap, anil' the lower lang or emloflti'tp is ins-erred, in the niertise ol' the frame and held by a 'rinnosable horizontal screw or pin.,

For greater strength, l show the iframe and barrel constructed in one piene. This is el'- .iccte hy making hollow blanks and rolling said blanks het over dies or nnnnlrels or For short i'ranies,as pistols; by stamping in :l The magazine may he inclnded er formed separately. The brace locks the bolt hy bearing obliqnel y upward. against the top of the franief. and the ledges e e in the fraaie support the bolt against the downward prost-,nre of the brace, and thereby assist the brace to resist the discharge.
